lb all 'u'ho-ni it may concern:

N umber 112,621, now pending in the Patent Ofiice. Such loaders comprisea frame mounted on a carr age so that it may be h tched on behind a .aon in such manner as the machine progresses. Arranged over I said frameare sets of raker-bars, which are mounted so that in operation they moveup in close proximity to the frame and return at. a considerabledistance therefrom, so that they carry up the hay as they move upwardbut do not come in contact withit during Said raker-bars are theirreturn movement.

operated from the main axle by suitable driving mechanism.

My present invention has for its object to PIOVHlQ a new and improvedhay loader 1n which the movement of the lower ends of the raker-barswill be such that the ground rakes.that is, the rakes nearest theground-will more than rake the ground traversed by the forward motion ofthe machine,-that is to say the length of operative stroke ofthe groundrakes will be greater than the distance traveled by the machine duringthe time occupied in making such stroke. The advantage of this operationis that it insures the complete raking of the ground, since a margin ofsafety provided which insures a amst leaving unraked spaces.

A further ObJQCt of my invention i to provide a new and improvedconstriu-tion of hay f loader by which the danger of choking at thethroat or upper end portion of the loader is avoided.

In hay loaders of the type illustrated in the accompanying drawings.which converge toward the top, so far as I am aware no especialprovision has heretofore been made at the throal or v1 pcr portion ofthe loader for passing the same q'iantity of hay as is taken up at thebottom of the machine where it is wider further than arranging therakcrbars so that they may move up and down or Dam, a citizen 1 towardand from the deck of the elevator frame. This, however, has been foundto be insuiiicient. As the yield in difierent fields l varies, and theproduct which is being loaded is seldom evenly distributed over the lground, and the windrows into which the crop may be gathered are not ofuniform Y size, in the absence of especial provision for accommodatingunequal masses or bunches of hay at the throat of the loader or upperportion of the elevator frame serious consequences follow. Experiencehas shown that under said conditions in the loaders as here i toforeconstructed a large bunch elevated to l the throat of the loader isstopped or impart of the bunch has become disintegrated i or pulledapart by the action of the rakerbais, and that part which is held backdur- 5 ing this period is subjected to the motion of the raker-barswhich have a heating or threshing effect upon it because of its not;moving upward and forward under their action,the result being that theleaf is destroyed and the stalk broken, thereby dami aging the hay.Should the hay continue to be proportionately heavy for a considerabledistance, the space between the raker-bars and the slats forming the bedor deck of the elevator frame would become congested or i packed untilthe machine would clog, and the drive-wheels slide,-the machine nothaving 5 sufficient power for driving the raker-bars under saidcondition of congestion. It may be well to explain that it isimpractical to i overcome the objections above noted by making thethroat of the loader large enough to accommodate the larger bunches ofbay for the reason that when working in light bay 5 such portion of themachine would necessarily have to be filled before the hay wouldcommence to pass through it on to the wagon. and the hay so delayeduntil the space be came filled would be subjected to the same actionfrom the rakcr-bars as when the omntity was too great to pass throughthe throat without delay.

My present invention provides a construction by which the objectionsabove noted are avoided and ample provision made for accmnmodaiing thelarger bunches w thout de- 5 tracting from the cflicicncy of the loaderwhere the hunches are small.

In the accmnpanz'ng drawings I have illustrated my improvements asapplied to a f loader of the type illust 'atcd in my applicapeded by thelimited space until the upper v thatthe hay will be dehvercd to thewagon l bars 15 carried by the loader frame.

tion above referred to, but it will be understood that my invention isnot restricted to machines of that type alone, but may be employed inany other machine to which they are adapted.

in the accompanying drawings,Figure 1 1s a side elevation of anay-loader embodying -iy invention, certain parts being bronen away;big. 2 is a per spective View of a part of the elevator frame, showingone form of clip by which the slats composing the bottom or deck of theelevator frame are secured in position; Fig. 3 is an edge view of theupper crossbar of the elevator Iramc and one or the slats,-the latterbeing in section; big. a is a partial plan View or the elevator frame;big. 5 is a perspective view oi another form of clip; h1g5. e and 7 areviews illustrating dilierent arrangements of devices for securing theslats or the upper crossbar,-the latter being shown in section; big. 8is a sec tipnal detail, illustrating part of the upper portion of theelevator name, and big. a is a rear' elevation of my improved hayloader.

Referring to the drawings for a detailed description of the constructiontherein SiJO\\1l,--l indicates the loader frame; 2 the upright portionsof the carriage; 3 the substantiall y horizontal portions of thecarriage 4 one of the wheels; and 5 the axle. The portions 23 of thecarriage are rigidly connected together, as shown at 6 in -l*'ig. l, andthe members 3, one of which is provided at each side of the machine, aresecured to the frame 1.

if desired, the members 3 may be made extensible, as shown in my saidapplication, and with that end in View the frame 1 is pivotally mountedat 7 upon the upper end portions of the vertical members 2 of the frame.

The members '2 are =pivolaily inouuted upon the axle softhaf the' loaderframe may be rocked about the axle-as a center.

8 indicates uprights or standards, one of which is provided at each sideof the lower portion of the loader frame 1, as illustrated.-

9 indicates double cranks, one of which is provided near each end of thaxle 5..

10 1]. indicate rake frames composed of a series of raker-bai's whichcarry rake-teeth 12. This construction is fully illustrated in mypending application hereinbefore referred to. At their upper ends therake frames are supported and guided by brackets 13--l-.t. respectively,which slide on guide At their lower ends the rakeiramcs are pr-tvidcdwith arms 16-17, respect. :ely, by which they are connected withtransvenr bars 18-49, respectively, which serve to unite the componentraltenbars of each val-1e frame into a unified frame, and said bars areconnected by'llHlIS 20-21, respectively. with sliding blocks 22 whichare mounted on the standards 8, as shown. Said blocks may be verticallyadjusted and held at different positions of adjustment by any suitablemechanism, suclras sliding collars23 having set screws 24, the blocksbeing suspended from said collars 23 by links or other suitableconnections 23, as shown. Instead 1 or providing set screws 24, suitablemechanism may be employed for facilitating the vertical adjustment ofthe blocks 22. All these features of construction are fully illustratedand described in my said pending application.

2526 indicate pitmen, a pair of which are provided at each side of themachine Said pitmen connect the opposite crank portions of double cranks9 at each end of the axle with the arms 16-17, respectively,- saidpitmen being connected with said arms at points removed from the pointsat which the said arms are attached to the raker-bars. As illustrated,the pitmen are attached to the arms 16-17 at points 27-28, respectively,while the arms 1617 are pivotally attached to their respectivetaker-bars at the points 29-3(), respectively.

with the collars 23 at'their upper ends and with the pitmen 25-26 attheir lower ends, as shown. Said links constitute traveling or swingingfulcra for the pitmen, so that said pitmen may reciprocate as well asrock, and control the paths of the rakes. Said paths may be 'aricd byvertically adjusting the collars or. equivalent devices to which thelinks 31-32 may be connected.

It will be observed that, as has been suggested, in many respects theconstruction illustrated is similar to that shown and described in mypending application,the important differences, so far as my presentapplication is concerned, being that the pitmen are connected with theraker-bar arms at a distance from the points at ivhich said arms 'areconnected with the raker-bars. such distance being greater than thedifference between the length of the cranks 9 and the radius of thesupporting wheels by which construction the rakcr-bar is given a longeriional: distance gained being substantially equal to the distancebetween the point where the pitman attaches to the raker-bar arm and thepoint. where said arm attaches to the raker-bar.

As shown in Figs. 1 and 4,. the bottom oi the elevator frame 1 iscomposed Ofdongrtinlinally-disposed slats set a distance apart andsupported by crossbars 34-35- (he elevator frame. The uppermost crossbar36 is placed a considerable distance from. the upper ends of the slats33, so that the upper ends of said slats may freely be flexed l or bent.downward-to increase their distance motion or sweep over the ground,theaddi ti,tl1e latter being secured to the side of 3132 indicate linkspivotally connected I from the raker-barsx This is indicated in dottedlines in Fig. 1. By this construction when large bunches of hay reachthe upper portion or throat of the loader the upper ends of'the slats 33yield under the increased strain to which they are subjected, permittingthe hay to pass unimpeded. Obviously, also, they accommodate themselvesto smaller bunches. In order to provide greater flexibility for theslats they are not rigidly secured to the crossbar 36 but are so securedas to have a limited amount of play thereon. 'lfo this end I havedevised devices of various forms.

In the construction illustrated in Fig. 2 I provide the crossbar'36 witha staple 37 which extends longitudinally thereof, and I provide theslats 33 at their under sides with clips 38 having tongues 39 adapted toslip.

under the staple 37 111 the manner shown in Fig. 2. The clips 38 areprovided with projections 40 at opposite sides, which extend through orembrace the slats and engage them firmly.

In Fig. 3 I have illustrated the projections 40 as extending through oneof the slats 33. In use the tongue 39 projects upward longitudinally ofthe slat, and, when in engage- .ment with the staple. serves to hold theslat against lateral movement, butpermits longitudinal movement. of theslat, so that when the slat is bent downward I utilize the clasticity ofa portion of the slat below the upper crossbar 36 as well as of theportion above it; whereas, if the slat were rigidly secured to thecrossbar 36, this result. would not ensue.

In Fig. 5 I have shown a modified arrangement of clip consisting of aplate 41 having projections 4'2, 43 and 44, which embrace the slat, anda tongue 45 formed by making a U-sha ed slit in the plate 41 andpressing down t 1e central portion thereof.

In F 1g. 6 I have shown a clip formed of a staple 46 bent at rightangles so that the rounded portion thereof is substantially parallelwith and at a distance from the lower face of the slat. A similarconstruction is shown in Fi 7, in which a staple 47 is bent twicesubstantially at right anglesforming shouldcis 48 which preventdisplacement of the clip with reference to the slat. By securing theslats of the z pper crossbar in the manner above dcscriLa-d I l l l l xassist very materially in securing the results desired. since the stapleto which the clip is hooked forms a fulcrum over which the slat rocks.thereby increasing its flexibility and adding to its ciliclcnev hygiving it a larger scope or movement. A further advantage of thisconstruction is that the elevator frame may readily be taken apart andput together I without danger of damaging it as would be the case if theparts were nailed together.

and besides there is no danger of interfermachine during said stroke.

ing with the progress of the hay, since the clips being on the underside of the slats they are out of the way. Nails, on the other hand,would be apt to work loose owing to the springing up and down of theupper ends of the slats and would then project into the path of the hayand impede its progress.

So far as I am aware, I am the first in the art to provide aconstruction by which the stroke of the ground-rakes is made greaterthan the distance normally traveled by the I therefore claim thisfeature in the broadest manner possible, and wish it to be understoodthat my invention is not restricted to details of the constructionillustrated and described. except in so far as they are specificallyclaimed, but includes eneri ally the sub ject-matter of the broaderclaims.
